"The Rds 86 operates on a secondary frequency band (reserved for military geophysical surveys). At post-midnight hours, ionospheric ducting may reveal deep stratigraphic or subsurface structural returns. Such echoes are considered CLASSIFIED ARTIFACTS. Power down immediately upon detection."
She checked the elevation tilt. Negative 2 degrees. Impossible—the radar horizon should have cut off anything below the terrain. Yet there they were: a lattice of returning pulses, like a subway map of a city that didn’t exist, threaded through the granite of the mountain itself.
